Vaccination against tick-borne encephalitis (TBE) is usually recommended for anyone who plans to live or work in a high-risk area, or hike and camp in these areas during late spring or summer.

The ticks that cause TBE are mainly found in forested areas of central, eastern and northern Europe, although at-risk areas also include eastern Russia and some countries in east Asia, including some regions of China and Japan.

The vaccination requires a course of 3 injections for full protection. The second dose is given 1 to 3 months after the first and provides immunity for about a year.

A third dose, given 5 to 12 months after the second, provides immunity for up to 3 years.

The course can sometimes be accelerated if necessary. This involves 2 doses being given 2 weeks apart.

Booster doses of the vaccine are recommended every 3 years, if necessary
